5.0 out of 5 stars Great for rentals
Reviewed in the United States on 29 October 2019
We are renting a townhouse in a pretty rough area of the city and needed something like this. The alarm is small and was super easy to install; it only took a few minutes. Our doorframe is not aligned with the door, so I put 5 layers of thick double-sided tape under the main part of the alarm (the part that sticks to the door) until it aligned with the smaller part on the doorframe. It works perfectly! We installed it on our front door, located on the first floor. We can hear the alarm all the way upstairs in our bed. This purchase has brought me so much peace of mind!
